Description

  The present invention belongs to a technical field related to a step board installed at a stepped portion such as a building entrance, a user entrance, an edge side of a building, and more specifically, the height position can be freely slid to be adjusted to a step having different heights. It relates to a sliding step.

  Conventionally, a step board has been put to practical use in order to eliminate the steps existing at the entrance of the building, the entrance, and the edge of the building. As such a step, there is a demand for a slide-type step that can freely adjust the height position so that it can cope with steps of different heights, and is disclosed in Patent Document 1 below.

The sliding step of Patent Document 1 is composed of an inner box and an outer box having an opening on the upper surface for accommodating the inner box so as to be slidable in the vertical direction. A locking plate made of a spring or the like that is in contact and supported at a predetermined height and always applies an outward tension and a rotating plate with a shaft provided with a knob protruding outward are connected via a connecting rod. It is configured.
Therefore, when the knob is twisted, the rotating plate with the shaft rotates, and when the connecting rod connecting the locking plate is pulled inward, the locking plate moves inward, and the upper end of the locking plate The inner box supported by the base plate is detached from the locking plate, and slides into the outer box under its own weight to be housed in a low step. Conversely, when the inner box is lifted upward from the above state, the inner surface of the inner box slides in contact with the locking plate that exerts tension outward, and when the height of the locking plate is exceeded, It is configured to open to the outside by the tension of the plate and support the lower end portion of the inner box in a contact state so as to be changed to a stepped step.

Japanese Utility Model Publication No. 61-152699

The point which can adjust the height of an inner box is recognized for the slide type step of the above-mentioned patent documents 1.
However, the slide mechanism has a complicated structure in which a locking plate such as a spring is moved inward by a knob to raise and lower the inner box, which increases the cost. In addition, since the weight of the user is supported by a locking plate made of a spring, there is a risk that a lateral shift or the like may occur, and safety and reliability are lacking.
Moreover, the height which can adjust this slide type step is only two steps of the height in which an inner box comes to the upper end part of a locking plate, and the height in which an inner box is accommodated in an outer box, and is located in the bottom part. . Therefore, it cannot cope with various different steps.

  The object of the present invention is to solve the above-mentioned problems, and the cost can be minimized as a very simple structure, the user's weight can be reliably supported, and safety and reliability can be exhibited. The object is to provide a highly convenient slide-type step by finely adjusting the position over a plurality of stages.

As a means for solving the above-mentioned problem, a sliding step according to the invention described in claim 1 is:
It consists of a tread box and a base frame,
A vertical groove hole extending in the vertical direction on a pair of side surfaces facing the tread box , and a horizontal groove extending in the direction in which the step box and the front side of the base frame are in contact with each other in the form of a plurality of combs horizontally from the vertical groove hole hole and slide hole portion is provided made of, and the fastening hole is provided at a height position corresponding to the lateral grooves holes on a set of side surfaces faced each other of the base frame,
The step box and base frame are fastened with a fastener inserted into the slide hole and fastening hole, and the height position of the step box can be freely adjusted within the range of each slot of the slide hole. It is characterized by that.

The invention described in claim 2 is the slide type stool described in claim 1,
The front end portion of the lateral groove hole of the slide hole portion is formed in a shape inclined in a direction in which the fastener bites in response to a load acting on the tread box.

The invention according to claim 3 is the slide type stool according to claim 1 or 2,
The height position of the fastening hole is made to correspond to either the uppermost stage or the lowermost stage of the lateral groove hole so that the height position of the tread box of the slide type stool is the highest.

The slide step described in claims 1 to 3 has the following effects.
The slide step of the present invention is composed of a step box and a base frame, a vertical groove hole extending in the vertical direction on a pair of side surfaces facing the step box , and a plurality of combs in the horizontal direction from the vertical groove hole. The slide hole part which consists of a horizontal groove hole extended in the shape is provided. Further, a pair of side surfaces faced each other to the base frame the corresponding fastening hole in a height position corresponding to the lowermost or uppermost of said transverse grooves hole is configured to be provided, the fastening hole and the slide hole section Fastened through the fasteners and assembled into a slide step.

Therefore, the vertical height of the platform is determined by sliding the step box up and down around the fastener through the vertical slot, which is the slide hole, to the appropriate slot position among the horizontal slots provided in a multi-stage comb shape. It is economical because it can be freely adjusted with a very simple structure of sliding and fixing in the horizontal direction, and the height position can be adjusted freely with horizontal groove holes provided in multiple steps at a fine pitch. It is very convenient because it can respond immediately to different steps.
Also, the range of height adjustment can be freely changed by simply increasing the length of the longitudinal groove holes and the number of lateral groove holes, which are slide hole portions, and is therefore highly versatile.

Furthermore, the front end portion of the lateral groove hole of the slide hole portion is formed in a shape inclined in a direction in which the fastener bites in response to a load acting on the tread box.
Therefore, when the user rests on the upper surface of the tread box, the load is distributed in two directions due to the inclination of the horizontal groove hole, and it is ensured that the load is concentrated on the tip of the horizontal groove hole due to the resultant force and a lateral shift occurs. It can be prevented and can exhibit safety and reliability.

The present invention is a sliding step 1A composed of a box-shaped step box 2 having an open bottom surface and a rectangular base frame 3.
A pair of side surfaces of the tread box 2 facing each other has a slide hole portion 4 formed of a vertical groove hole 40 extending in the vertical direction and a horizontal groove hole 41 extending from the vertical groove hole 40 in a multi-stage comb shape in the horizontal direction. Is provided.
The lateral groove hole 41 of the slide hole portion 4 provided on a pair of side surfaces of the tread box 2 facing each other is formed in a shape in which a tip end portion is inclined upward.
A fastening hole 6 is provided at a position corresponding to the uppermost step of the lateral groove hole 41 on a pair of side surfaces of the base frame 3 facing each other.
The step box 2 having the above-described configuration is covered so that the side peripheral surface thereof is located outside the base frame 3, and the fastener 10 is screwed into the fastening hole 6 through the slide hole portion 4 and fastened. The height position of the tread box 2 can be freely adjusted within the range of the four slots 40 and 41.

Hereinafter, the present invention will be described based on illustrated embodiments.
EXAMPLE sliding platform 1A of the present invention particularly shown in FIG. 1-6.
The sliding step 1A includes a box-shaped step box 2 on which a non-slip mat or the like is attached so that a user can put his / her foot on the lower surface, and a rectangular base whose upper and lower surfaces are open. It consists of frame 3. Both are formed by bending and welding an iron plate, but may also be formed by joining wooden plates. Incidentally, when the tread box 2 can exhibit sufficient rigidity, the rear surface side can be excluded.

  The slide type step 1A shown in the first embodiment is a type in which the step box 2 completely covers the base frame 3, and therefore the outer dimension of the base frame 3 is slightly smaller than the step box 2. ing. Further, as shown in FIG. 6, the left and right side surfaces of the base frame 3 have a length shorter than that of the step box 2, and have a space in front and rear when the step box 2 is covered. Although this is mentioned later, when changing the height position of the tread box 2, it is for allowing the tread box 2 to move back and forth.

A pair of left and right side surfaces of the tread box 2 facing each other are provided with a slide hole including a vertical groove hole 40 extending in the vertical direction and a horizontal groove hole 41 extending horizontally from the vertical groove hole 40 in a four-stage comb shape. Part 4 is provided. In addition, a handle 5 is provided at the upper center position to facilitate the back and forth movement of the tread box 2. The handle 5 is basically an oval through-hole, but of course, a metal fitting may be attached to improve the appearance.
It is preferable that the lateral groove hole 41 of the slide hole portion 4 provided on the left and right side surfaces of the tread box 2 is formed in a shape in which a tip portion thereof is inclined upward.
This is because when the step box 2 and the base frame 3 are assembled and installed as the slide type step 1A, when the user places on the upper surface of the step box 2, the load is transferred to the horizontal groove by the fastener 10 passed through the horizontal groove hole 41. The hole 41 receives the load, and the load is distributed in two directions, upward and obliquely upward, due to the shape of the lateral groove hole 41, and the resultant force concentrates the load on the distal end of the lateral groove hole 41 and causes lateral displacement. This is because it can be surely prevented (see FIG. 3A). The slide hole portion 4 is not limited to that shown in FIG. 3A, and as shown in FIG. 3B, the lower surface of the vertical groove hole 40 may be cut away so that the tread box 2 can be removed. In the illustrated example, the number of steps of the lateral groove 41 is four, but a highly versatile slide step can be implemented by appropriately increasing or decreasing the number of steps.

The pair of left and right side surfaces of the base frame 3 are arranged on the left and right side surfaces of the base frame 3 so as to secure a position where the step box 2 is the highest as a step. A fastening hole 6 that is tapped is provided at this position. Further, the base frame 3 can be completely accommodated in the hollow portion of the tread box 2 and fixed at the lowest height position by an appropriate total length of the longitudinal groove hole 40 of the slide hole portion 4.
Further, the base frame 3 in the illustrated example is provided with a notch 9 at the center upper edge thereof in accordance with the shape of the through hole of the handle 5 of the tread box 2.
The upper and lower surfaces of the base frame 3 are in a released state in the illustrated example. Therefore, as shown in FIGS. 4A and 4B, the flange 7 extending from the left and right side surfaces of the base frame 3 is joined by welding or the like, and the anchor 8 is embedded from the anchor hole (not shown) provided in the flange 7 toward the installation surface. It is preferably carried out by fixing to the installation surface. The flange 7 may be implemented by using an L-shaped angle member and connecting the vertical portion and the left and right side surfaces of the base frame 3 by welding or bolt joining. Of course, the present invention is not limited to this, and as shown in FIG. 5A, the base plate 11 is preferably attached to the lower surface of the base frame 3. At that time, as shown in FIG. 5B, it is possible to carry out by standing the handrails 12 at positions corresponding to the four corners of the slide step 1 </ b> A of the base plate 11. Incidentally, the base frame 3 of FIG. 4A shows an example in which the frame material on the rear surface side is excluded.

The step box 2 and the base frame 3 configured as described above are covered with a side peripheral surface of the step box 2 so as to be positioned outside the base frame 3, and as shown in FIG. The tool 10 is screwed into the fastening hole 6 of the base frame 3 through the slide hole portion 4 of the tread box 2 and fastened (see also FIG. 4B).
Accordingly, the height position of the step box 2 can be freely moved and adjusted within the range of the grooves 40 and 41 of the slide hole portion 4 without removing the step box 2 from the base frame 3.

Here, the adjustment method of the height position of the slide type step 1A will be described based on FIGS. 6A to 6C in the case where the step box is raised from the lowest position to the higher position.
The sliding type platform 1A which is completely assembled as shown in FIG. 2 (FIG. 6A), first, previously loosen the fastening of the fastener 10 so as to Shifts the stepping box 2 in vertical and horizontal directions. Then, hold the handle 5 of the step box 2 and move it forward. Then, the fastener 10 fixed to the fastening hole 6 moves backward in the horizontal groove hole 41 of the slide hole portion 4 and is guided to the vertical groove hole 40. Then, when the tread box 2 is lifted upward until it reaches an appropriate height position in the vertical groove hole 40 (see FIG. 6B), it is pushed back at an appropriate groove hole 41 position of the four-stage lateral groove hole 41. (See FIG. 6C), the fastener 10 is guided to the distal end portion of the appropriate lateral groove hole 41 by the weight of the tread box 2, and the fastener 10 can be fastened and fixed to an appropriate height.
Therefore, the height position of the tread box 2 can be slid and freely adjusted without removing the tread box 2 from the base frame 3 and without changing the attachment position of the fastener 10.
In addition, since it is easy for people to ride on the front side, there may be an unstable impression if a gap appears on the front side of the top plate (step box 2). front side contacts the (no gap) transverse groove holes 41 in the direction which extends from the longitudinal groove hole 40.

As a reference example 1 of the actual Example 1, it showed the outline 7 and 8.
The sliding platform 1B is substantially the same technical concept as the actual Example 1, hereinafter, it is described only the differences.
In short, the slide type step 1B is of a type in which the mounting positions of the slide hole portion 4 and the fastening hole 6 are opposite to those of the slide step 1A. The base frame 3 of the slide step 1B is formed such that the upper and lower surfaces are opened and / or the rear surface is opened. Therefore, when the tread box 2 and the base frame 3 are fastened, when the tip of the fastener 10 protruding from the inner surface of the base frame 3 is fastened by the nut 10b, a work can be performed by inserting a hand from the open surface.
Slide holes 4 having vertical groove holes 40 and horizontal groove holes 41 are provided on the left and right side surfaces of the base frame 3 facing each other. Fastening holes 6 are provided at the height positions. Incidentally, the fastening hole 6 does not need to be tapped.
When the slide hole portion 4 is provided in the base frame 3, the lateral groove hole 41 is provided in a shape in which the tip end portion is inclined downward. With the shape as described above, as shown in FIG. 8, when the user is placed on the upper surface of the tread box 2, the load is distributed in two directions, downward and diagonally downward. This is because it is possible to reliably prevent a load from being concentrated on the tip of the hole 41 and causing a lateral shift.
The tread box 2 and the base frame 3 configured as described above are covered with the fastener 10 having the washer 10a so that the side peripheral surface of the tread box 2 is positioned outside the base frame 3. And a nut inserted through the slide hole 4 of the base frame 3 and the leading end of the fastener 10 protruding from the slide hole 4 from the open lower surface / or rear surface of the base frame 3. Fasten and fasten with 10b.

The sliding step 1C of Reference Example 2 of Example 1 shown in FIGS . 9 and 10 can also be implemented based on the same technical idea. FIG. 9 is an exploded perspective view of the sliding step 1C, and FIG. 10 shows an example of the installation situation. Since the reference example 2 has substantially the same configuration as that of the first embodiment, only the difference will be described below.
As is apparent from FIG. 10, the sliding step 1 </ b> C is a type in which the step box 2 enters inside the left and right side surfaces of the base frame 3. Therefore, the shapes of the tread box 2 and the base frame 3 are opposite to those of the first embodiment, the inner dimensions of the base frame 3 are larger, and the tread box 2 is small enough to enter the inside of the base frame 3. .

The left and right side surfaces of the base frame 3 are provided with slide hole portions 4 including vertical groove holes 40 and horizontal groove holes 41 extending from the vertical groove holes 40 in a four-step comb shape in the horizontal direction. Therefore, as described above, the lateral groove hole 41 provided in the base frame 3 has a shape in which the tip portion is inclined downward. Further, slits 30, 30 into which the left and right side surfaces of the tread box 2 can be inserted are provided at the inner positions of the left and right side surfaces of the base frame 3.
Fastening holes 6 are provided on the left and right side surfaces of the tread box 2 at a height position corresponding to the lowest step of the lateral groove hole 41, and are tapped.
The left and right side surfaces of the tread box 2 having the above structure are inserted into the slits 30 and 30 of the base frame 3, and the fastener 10 provided with the washer 10a is screwed into the fastening hole 6 through the slide hole portion 4 and fastened and fixed. The slide step 1C is assembled.

The present invention can be implemented also in the slide step 1D shown in FIG. 11 based on the same technical idea.
This slide type step 1D is provided with slide holes 4 on the left and right side surfaces of the step box 2. Therefore, as shown in FIG. 1, the lateral groove hole 41 has a shape in which the tip end portion is inclined upward. Further, fastening holes 6 that are not tapped are provided on the left and right side surfaces of the base frame 3 at a height position corresponding to the uppermost step of the lateral groove hole 41 of the slide hole portion 4. Further, this sliding step 1D is a type in which the step box 2 shown in FIGS. 9 and 10 enters the inner side surface of the base frame 3, and slits 30 and 30 are provided on the inner sides of the left and right side surfaces of the base frame 3. The lower surface and / or the rear surface is formed in an open state.
The left and right side surfaces of the tread box 2 having the above configuration are inserted into the slits 30 and 30 of the base frame 3, and the fastener 10 having the washer 10a is inserted into the fastening hole 6 of the base frame 3, and the slide hole of the tread box 2 The tip of the fastener 10 protruding from the slide hole 4 is fastened and fixed by a nut 10b inserted from the open lower surface or the rear surface of the base frame 3.
This sliding step 1D has an advantage that the design is high because the slide hole portion 4 is completely hidden on the left and right side surfaces of the base frame 3 in the fully retracted state.

  Although the present invention has been described based on the illustrated embodiment, the present invention is not limited to the configuration of the above embodiment. It should be noted that it includes a range of design changes and application variations made by those skilled in the art as needed without departing from the scope and purpose of the invention.
